入门级JSP：<jsp:include>的一些问题

Question

我先贴出自己两个jsp文件的代码

include.jsp:
<%@ page contentType="text/html; charset=gbk" language="java"%>

" />
/jsp:include

action.jsp
<%@ page contentType="text/html; charset=gbk" language="java"%>

This is a1=<%=request.getParameter("a1") %>

接下来是报错：
HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.include_jsp

---

type Exception report

message java.lang.ClassNotFoundException: org.apache.jsp.include_jsp

description The server encountered an internal error that prevented it from fulfilling this request.

只要写到jsp:include 和jsp:forward这些传递参数的都会出现这些问题，希望能力的帮我解决一下，感激！！！！！
